The Lowdown

Alright, Rusty here, and let’s have a look at what’s cookin’ for Jaconé over the next couple of weeks.

Right from the get-go, we’re not looking at much until Saturday morning the 29th. The Friday afternoon is a write-off—just a small, weak S swell with a strong cross-off wind making things messy. Water temp’s sittin’ at 72°, which is pretty normal for this time of year, so nothin’ to write home about there.

Saturday morning the 29th is where the first real window opens. We’ve got clean conditions with a light NE offshore breeze, and the swell is comin’ from the east at 4ft with a short period of 7 seconds. The wave energy is moderate (322) but that short period means it’ll be a bit mushy and inconsistent. Still, it’s surfable for a few turns. By the afternoon, it drops off fast.

Sunday the 30th is a no-go with onshore and cross-on winds, and Monday morning the 31st is only so-so, but Monday afternoon the 31st finally gives us something to smile about. The wind swings light offshore from the ENE, the swell pushes up to 4ft from the east, period’s still only 8 seconds, but with that clean glassy surface, you’ll find a few fun little wedges. Wave energy's up to a solid moderate (339). That’s a decent afternoon session for the intermediate crew.

We hit a dry spell again Tuesday and into Wednesday, with strong onshore wind and big, ugly swell. On Wednesday the 2nd of September, the swell jumps to 13ft from the SSW with a very long period of 13 seconds and massive energy (9722)—but it’s blowin’ onshore at 15 mph. That’s not surf, that’s a washing machine. Kite surfers might be havin’ a field day, but paddle surfing’s a no.

Then things get interesting. Thursday the 3rd of September morning is the first real standout. The swell drops to 8ft from the SSW with an 11-second period and moderate-to-strong energy (1134). The wind is light from the NNW, cross-off, and the conditions are pristine. That’s excellent surf, but at 8ft it’s strictly for experienced surfers. If you’ve got the chops, this is the session to circle.

Saturday the 5th of September morning is another good call with a light NE offshore and a clean 2ft SSE swell—small but clean, perfect for the longboard or a fun cruiser.

Sunday the 6th of September morning is another gem. The wind goes glassy, dead calm, swell sits at 7ft from the SSW with moderate energy (1452). Again, that’s expert territory due to size, but if you’re in, it’s gonna be world-class clean.

Monday the 7th of September morning keeps the trend: light wind, glassy conditions, 8ft S swell with 11-second period and strong energy (1354). Another top-tier window for the experienced crew.

Tuesday the 8th of September morning is the last real standout before things get messy again: 7ft S swell with a long 13-second period, light offshore from the ENE, and gentle, clean conditions. Energy’s strong (1325). That’s a morning of proper groundswell barrels.

After that, we get a bit of a fade-out. The swell drops, the winds get cross or onshore, and the energy levels fall off. There’s a couple of marginal windows on the 10th and 11th of September with long period SSE swells but winds that’ll make it tricky. The 12th of September sees some solid SSW swell, but with fresh offshore winds and heavy rain—might be worth a look if you don’t mind a bit of weather.

Overall, the best on offer in this stretch is the morning of the 3rd of September and the morning of the 6th of September. Glassy, decent size, clean lines—classic Jaconé when it all lines up. First week’s mostly for intermediates, second week’s for the hardcore crew. Keep your eyes on those windows.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
